T'.aZZ whom (it may concern:

Be iliknown that I, ALoonx Ramon, of

the city county, and State of New York, have invented a new and usefulImprovement in Telephone Adjuncts, of which the following is a full,clear, and exact descripnun. 1 i

p My invention relates to-improvements in that class oftele'p'luznejapparatus whiclr'are used in connection with a telephonetoassist hear ng, but wh ch are not attached to the telephone Moreparticularly my invention relates to improvements in telephone headpieces s uch 15, as are worn on the head with ear cups to .fit

- both ears, and'wi'th means for having sounds from a telephone receivertransmitted to" both ear pieces of the head piece I I am not the first,inthis application, to

-:."show and describe a telephone head piece; having earcups to fit bothears and having means for connecting in some manner with a telephone,but in apparatus of this class -.hereto'fore n'iade, 'clitticulty hasbeen expel-'1.-

enced in producing a device which wouldfit. any ordinary head so thatthe ear pieces wouldfit naturally and comfortably over the ears. Suchstructures h'ave'been recognized asbeing valuable-because.they-'exclu'de' eitp traneoushsoiinds and enable the slightest soundsthrough the receiver .to be trans-' mitted to hothear pieces; :Moreoverthey are-not attached to the telephone',fand that leaves one hand freefor making memoranda,

etc

- It is not practically feasible tolprovide for "adjusting the headpieces 'to d fferent" ,'hea d's,because this means complication and-'-,expense, and such devices must be simple, as i'.fr'e'easspos'siblefrom joints, and easy or application without thebother of adju'st- H I I a Qan'y pecul arityottheshape' ofgthe head,"

lies .in. the spring. connection between the.

the ear pieces are held against wabbling and remain firmly inplace. Thejoints, it will be noticed, connecting the ear pieces and thespringforks, permit the ear pieces to turn.

on horizontal axes so as to'adjust themselves in any direction.Thespring forks are provided with flanges 22, a iidThere should be aplurality of these flangeson each fork so that the spring may be heldrigidly in one direction, but the flanges are pivoted on the upper endsof a connecting sprmg'QB of a general U shape which fits over some partof the head and which is sufficiently springy to cause the ear pieces topress with 'sufiicient force against the head of the operator to holdthe ear pieces 'in'place. It will be seen that the joint betweentheforks 19 and the spring 23 provides for turning the ear pieces onvertical axes, and thus they can adjust themselves either vertically orlaterally, and

will permit the ear pieces to adjust themselves vertically andlaterally, outwardly and inwardly, The joints which I have shownconnecting the spring forks 19 and the spring 23, hold the forks againstdoubling over inwardly or outwardly on the spring 23, but permit them toturn laterally.

In Fig. 3 I have shown a modificationin which the ear pieces 10 aresimilar, and mounted as shown and already described, but in which thetube 14 is divided and connects with a tube 1% through which the soundmay come from any source whatever. This form of the device is applicablefor use in connection with any other sound prodncing machines forinstance for hearing the sounds from a phonograph or other form ofmusical and talking machine. the apparatus in any case is not strictlylimited to use with a telephone, as it can be operated in connectionwith the conveyance of sound or with any sound producing machine orapparatus where it is desired to have the sound waves accurately andnicely transmitted to both ears and 'where it is desired to have atleast one hand left free.

Having thus fully described my inven- In fact tion, I claim as new anddesire to secure by Letters Patent:

1. A telephone adjunct comprising ear pieces independent of a telephonebut one of which is adapted to abut with the-end of the telephonereceiver, a sound transmit ting connection between the two ear pieces,a. tension spring adapted to clamp the ear pieces to the head, anda'flexible connection between the ear pieces and the tension springwhich permits the ear piecesto oscillate in one of the ear pieces beingprovided with a plate to fit against a telephone receiver, and

a sound transmitting connection through the plateto the ear piece, incombination with a curved spring arranged between the ear pieces, andspring forks pivoted on the spring and pivoted also to the ear pieces,whereby the latter can oscillate in two directions.

4.. An apparatus of the kind described, comprising a pair 'of ear pieceshaving a sound transmitting connection between them, one of the earpieces being provided with a plate to fit against a telephone receiver,and a sound transmitting connection through the plate to the ear piece,in combination with a spring connection between the ear pieces whichpermits the latter to tip vertically and laterally.

A telephone adjunct comprising hollow ear pieces having a soundtransmitting connection between them, a single curved tension springarranged adjacent to the ear pieces and spring forks straddling the earpieces, the said forks being pivoted to the ear pieces at their ends andhaving their midc le portions journaled to the ends of the tensionspring.
